-LRB- CNN -RRB- -- Serena Williams has revealed she is not in love with playing tennis , despite an impressive straight sets victory on her return to action at the Brisbane International tournament .

Playing in her first match since losing the U.S. Open final to Samantha Stosur in September , Williams brushed aside South African Chanelle Scheepers 6-2 6-3 with consummate ease .

The 30-year-old American , who is seeded fourth in Brisbane , fired down seven aces in a 68-minute victory -- but later told reporters that she will cut back her schedule even further in 2012 .

Clijsters returns with convincing victory

`` I just want to be able to do other things that I 'm doing and expand on that . I think that helps keep my motivation up , '' said the 13-time grand slam winner .

`` I do n't love tennis today but I 'm here . I ca n't live without it -- there 's a difference between not loving something and not being able to live without it .

`` It 's not that I 've fallen out of love with it . I 've actually never liked sports and I never understood how I became an athlete , '' Williams continued .

`` I do n't like working out , I do n't like anything physical . If it involves sitting down or shopping , I 'm excellent at it . ''

In other matches , top seed and local favorite Stosur beat Anastasiya Yakimova of Belarus 6-2 6-3 and is on course to face Williams again in the semifinals .

Second seed Andrea Petkovic of Germany defeated Israeli Shahar Peer 7-6 1-6 6-3 , while former world number one Ana Ivanovic saw off Austrian Tamira Paszek 6-3 6-3 and now faces Kim Clijsters .
